The Neptune 4 Pro ships with Klipper pre-installed — enabling advanced input shaping, pressure advance, and configuration flexibility without modding.
Competitive CoreXY speed at a price significantly below Bambu and Prusa alternatives.
Full automatic bed leveling reduces setup time and calibration friction.
7 linear rails, 4 independent Z motors with Quad-Gantry Leveling, and a flying CoreXY gantry — the core architecture of the Voron 2.4, pre-assembled and ready to print.
Ships with Klipper pre-configured with Input Shaper, Pressure Advance, adaptive mesh bed leveling, and Obico remote monitoring — no configuration required to start printing.
One of the largest open-frame CoreXY build volumes at this price tier. The AC-powered bed heats quickly and handles ABS, ASA, PC, and PA with a 300°C capable hotend.
